Answer: 4.4 + (4 x 1/4 + 8.6) = 14
Step-by-step explanation: Because starting inside the parenthesis, 4 times 1/4 = 1. Then 8.6 plus 1 = 9.6. Finally, 9.6 plus 4.4 which equals 14. :)
 
        
             
        
        
        
Answer: Lashawna scored 14 points
Step-by-step explanation:
Let M = Mary's score
 L = Lashawna score
M = 28 points
And M is twice as much as L score
M= 2L
L= M/2
L= 28/2 
M = 14.
Lashawna score was 14 points
 
        
             
        
        
        
Answer:
5. 50.3 m²
6. 113.1 cm²
7. 102.1 yards²
8.  50.3 yards²
9.  452.2 ft²
10.379.8 ft²
Step-by-step explanation:
Area of  a circle = nr²
The circumference of a circle = 2nr
n = pi = 22/7
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = diameter / 2 
5. (22/7) x 4² = 50.3 m²
6.  (22/7) x 6² =113.1 cm²
7. radius = 11.4/2 = 5.7 yards
 (22/7) x 5.7² =102.1 yards²
8. radius = 8/2 = 4 yards
 (22/7) x 4² = 50.3 yards²
9. 2nr = 75.4 yards
2 x (22/7) x r = 75.4 
to find r, divide both sides of the equation by 2 and 7/22
r = 12 ft
Area =  (22/7) x 12² = 452.2 ft²
10. 2nr = 69.1 yards
2 x (22/7) x r = 69.1
to find r, divide both sides of the equation by 2 and 7/22
r = 10.99 ft²
Area = (22/7) x 10.99² = 379.8 ft²
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
 
        
             
        
        
        
3/4 = 6/x....3/4 = 6/8...notice that proportions are nothing but equivalent fractions
x = 8
